Ms. Jackson is serving fried turkey at 5:00 pm The 12-pound turkey has to coot 3 minutes per pound. What is the latest Ms. Jackson can star cooking

The turkey needs to cook 3 minutes per pound, and it weighs 12 pounds.

This means 3 x 12 will tell us the total minutes it will take to cook all the pounds.

3 x 12 = 36

 

The turkey will need to cook for 36 minutes, and he needs it ready at 5:00 pm

1 hour is 60 minutes, so 5:00 pm could really be:

4:60 pm

Let's subtract 36 minutes from this 

4:60

-  36

4:24

 

So the latest he can start cooking is 4:24 PM.
